Not necessarily. Some processors (Z80, for example) allow "prefixes" before the op-code.
The Z80's rotate-with-carry instructions, RRC and RLC, for Rotate Right and Rotate Left, are great for taking action based on individual bits being set or cleared. If you start with a clear carry flag, then get a byte from wherever, then you can rotate left or right one bit at a time. The bit you want to examine will eventually be in the carry. Then, execute a JP C, (location) or JP NC, (location) to jump based on whether or not the bit is set. (Of course, you could also use JR). The beauty of RLC and RRC is that they don't destroy the byte that you are using - after doing enough rotates, the byte will be as it was before.
AI Program (artificial intelligence) maybe?
what does a compression program do? what does a compression program do?
No. A server program receives and processes requests from a client program.
1.8085 has multiplexed data lines where as Z80 does'nt has multiplexed lines. 2.8085 operates at 3-5MHz clock freq,But clock frequency of Z80 is 4-20MHz. 3.8085 contains 74 instructions and Z80 has 158 instructions. 4.8085 has 5 interrupts but Z80 has only 2. 5.8085 has no index register but Z80 has 2. 6.8085 contains SIM & RIM instructions, but Z80 does'nt .
draw the Z80 processor and explain five of its pin function
Z80 contained 8.500 transistors. See the site I linked below for more information.
The TI-83 Plus has a clock speed of 6MHz. The newer TI-83 Plus Silver Edition and the entire TI-84 Plus series have a 15MHz clock speed, but usually run at 6MHz for compatibility with the older 83+. Assembly programmers can switch between the two speeds with a simple command. Unfortunately, BASIC programmers can not. They can use an assembly program that will do it for them, though.
The Z80 has 40 pins.

It depends on the particular simulator. You need to be more specific in your question.
Not necessarily. Some processors (Z80, for example) allow "prefixes" before the op-code.
A stored-program computer at least needs to know which instruction it has to execute next. Other memory addresses of special significance are e.g. the top of one or more stacks, or addresses to be used by instructions.To keep track of such addresses, all CPUs have one or more registers; for instance the address of the next instruction is stored in the instruction pointer, a.k.a. program counter. Which and how many registers of a CPU are designated to keep addresses depends on the CPU type. The Z80 for instance has a program counter, a stack pointer, two index registers and an indirect address register doubling as 16 bit accumulator, while the contemporay 6502 only has a program counter and a stack pointer.
